MANUFACTURE GF KNITTED WARE PLUSH Application filed July 30, 1927,Serial No. 209,426, and in Germany 4December 2, 1926.

The invention relates to a process for the manufacture of knitted warpplush, and ac'VV cording thereto rib warp threads, or rib weft threads,or both at the same time, are worked 5 into the ground fabric.

llhe insertion of .rib warp threads or of rib weft threads, or of bothtogether, makes it possible to give warp-knitted plush a s'olidity andrigidity, which makes it more useful for many purposes than heretofore,and also allows it to be used for many purposes for which it hashitherto been useless.

In order that the invention may be clearly understood and readilycarried into practice, we have appended hereto one sheet of drawings, inwhich the figure consists of a diagram, showing, by way of example, therun of the stitches in a fabric made according to the invention.

In the example illustrated, the fabric is made up of warp-knittingthreads a, plush warp threads b, rib warp threads c and o', and weftthreads d.

For the sake of clearness the plush thread b is only shown in theleft-hand longitudinal row or course of stitches. It will be understood,however, that the rib warp thread c may beomitted if desired.

The fabric is knitted with the aid of an additional plush needle bararranged on the appropriate side of the machinee The warp threads aforming the ground of the fabric are shown as forming stitches in tworows, in known manner.

The rib warp threads c are encircled by loops of the warp threads adrawn alternately from right and left of the rib warp threads, so thatthey are bound into the ground fabric, whilst the rib warp threads c runbetween the courses of stitches, being held between the meshes m betweenconsecutive stitches of the knitting warp threads, and the weft threadsd.

The plush thread Z) is knitted in with the stitches of the warp threadstv so as also to embrace the rib thread c, the consecutive stitches ofthe thread b beingengaged with one another, but the thread being drawnout into plush forming loops between the convsecutive stitches b ,thethread guides.

y suitable movements of T-he'weft threads cl are shown as insertedbetween the rib warp threads c, c and the knitting warp thread a. A

The machine employed for the manufacture of the fabric may be of anywell known and suitable type, but, of course,`has its operatingmechanism adjusted and arranged to lay the threads in the mannerrequired by the invention.

By means of the process according to the invention, it is possible toproduce novel kinds of plushes, especially suitable for curtains, wallhangings, or drapings, furniture, upholstery and pillow cases, divan andtable cloths, and travelling rugs. Moreover, if india rubber rib warpthreads are used, a fabric may be made which is suitable for themanufacture of bandages, corsets, and the like.

lWhat we claim is l. idarp knitted plush having a ground fabric ofparallel longitudinal courses of stitches, and including warp threadsforming meshes passing transversely of the fabric and making consecutivestitches in ldifferent courses, plush forming threads knitted intolongitudinal courses of stitches to form loops between consecutivestitches of said plush forming threads,l weft threads runningtransversely of the fabric and embraced by stitch loops of thelongitudinal courses, and unknitted rib warp threads running between thelongitudinal courses of stitches and held in place between the weftthreads and the knitted warp thread meshes.

2. Warp knitted plush including a ground fabric comprising knitted warpthreads in combination with weft threads and unknitted rib warp threadsrunning between the course of warp stitches and held in placebetween theknitted warp threads and the weft threads, and warp threads knitted intothe ground fabric to form plush loops on the surface thereof.

3. Warp knitted plush including a ground fabric comprising knitted warpthreads in combination with weft threads, unknitted rib .i n warpthreads embraced by the stitches of some of said knitted Warp threads7and other unknitted rib Warp threads running between the course of Warpstitches and held in place between the knitted Warp threads and the weftthreads, and Warp threads knitted into the lground fabric to torni plushloops on the surface thereof.

4. Warp knitted plush having a ground fabric of parallel longitudinalcourses of stitches7 and including Warp threads forming ineshes passingtransversely of the fabric and making consecutive stitches in differentcourses, plush forming threads knitted into longitudinal courses ofstitches to form loops between consecutive stitches of said plushforming threads, and weft threads running transversely of the fabric andembraced by stitch loops of the longitudinal courses.
